Usability evaluation can be the first step to improve e-learning systems. Since there is not an appropriate toll in Iran to completely evaluate it, the goal of this study was validating a foreign sample called UseLearn and its implementing in e-learning universities of Tehran. The research method was descriptive–correlational. A sample size of 288 was chosen through proportional allocation. The tool used in this study was UseLearn. The data were analyzed by confirmatory factor analysis, Cranach’s alpha coefficient, one-sample t test, ANOVA and MANOVA. Results showed that 12-factor model tested in this study was approved by AGFI. Also, factor loadings obtained for the questions (except question 29) indicated the validity of the questionnaire. Single-sample t test results indicated that the e-learning systems in e-learning universities of Tehran are not in a good situation in terms of usability. Results of MANOVA showed that there was a significant difference between the means of components of UseLearn questionnaire. Thus, UseLearn questionnaire can be used as a valid tool for assessing the usability of e-learning systems in the country.
